Colton earns $7 per hour plus $1.50 for each pizza delivery. the expression 7h + 1.50d can be used to find the total earnings after h hours and d deliveries have been made. how much money will colton earn after working 15 hours and making 8 deliveries?

Colton 
y = 7(15) + 1.50(8)
y = 105 + 12

y = $117

Here, Expression: 7h + 1.50d

Now, substitute for h = 15 & d = 8

= 7(15) + 1.50(8)

= 105 + 12

= 117

In short, Your Answer would be: $117

Hope this helps!

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
